Summary:PURPOSE:To improve sensitivity and potential stability at the time of durable use by using a specific disazo pigment in a photosensitive layer. CONSTITUTION:The disazo pigment expressed by the formula I is incorporated into the photosensitive layer formed on a conductive base. In the formula I, R1 and R2 are the same or different and denote a hydrogen group, halogen atom, alkyl group or alkoxy group which may have a substituent; A1 and A2 are the same or different and denote a residual coupler group having a phenolic hydroxyl group. The electrophotographic sensitive body which has the practicably high sensitivity characteristic and the stable potential characteristic at the tie of repetitive use is obtd. in this way.
